NASA Official Biography

NAME: Daniel M. Tani

NASA Astronaut Candidate (Mission Specialist)

PERSONAL DATA:

Born February 1, 1961 in Ridley Park Pennsylvania, but considers Lombard Illinois, to be his hometown. Single. He enjoys golf, flying, running, tennis, music, cooking. His mother, Rose Tani, resides in Lombard, Illinois. His father, Henry N. Tani, is deceased.

EDUCATION:

Graduated from Glenbard East High School, Lombard, Illinois, in 1979; received a bachelor and a master of science degree in mechanical engineering from Massachusetts Institute of Technology (MIT) in 1984 and 1988, respectively.

After Tani received his bachelor's degree from MIT, he worked at Hughes Aircraft Corporation in El Segundo, California as a design engineer in the Space and Communications group. In 1986, he returned to MIT and received his master's degree in mechanical engineering in 1988, specializing in human factors and group decision making. After graduation, Tani worked for Bolt Beranek and Newman in Cambridge, Massachusetts, in the experimental psychology department. In 1988, Tani joined Orbital Sciences Corporation (OSC) in Dulles Virginia, initially as a senior structures engineer, and then as the mission operations manager for the Transfer Orbit Stage (TOS). In that role, he served as the TOS flight operations lead, working with NASA/JSC mission control in support of the deployment of the ACTS/TOS payload during the STS-51 mission in September 1993. Tani then moved to the Pegasus program at OSC as the launch operations manager. In that capacity, he served as lead for the development of procedures and constraints for the launching of the air launched Pegasus unmanned rocket. Tani also was responsible for defining, training, and leading the team of engineers who worked in the launch and control room.

NASA EXPERIENCE:

Tani was selected as an astronaut candidate by NASA in April 1996. He reported to the Johnson Space Center in August 1996 to begin two years of training and evaluation. Successful completion of initial training will qualify him for various technical assignments leading to selection as a mission specialist on a Space Shuttle flight crew.

STS-99 Mission Status Report #06 - .
Nation: USA. Related Persons: Gorie; Kavandi; Kregel; Mohri; Tani; Thiele; Voss, Janice. Program: STS. Flight: STS-99. The Shuttle Radar Topography Mission's mapping operation continues to run smoothly, with about 17.7 million square miles of the Earth's surface having been mapped by 7 p.m. Central time. Scientists also reported that 38 percent of landmasses had been mapped thus far in the flight. Despite a problem with a small nitrogen thruster on the end of the 200-foot-long mast, both the C-band and X-band radars continue to perform as expected, and the thruster problem has had no impact on mapping operations.

STS-108 cargo bay payload was dominated by the Raffaello (MPLM-2) logistics module with 4 RSP and 8 RSR resupply racks. Also in the cargo bay were the MACH-1 and LMC experiment trusses flown under the Goddard small payloads program. MACH-1 was an MPESS-type Hitchhiker bridge carrying the CAPL-3 capillary thermal control experiment on top. On its forward side was the Starshine-2 launch canister, the CAPL-3 avionics plate, the Hitchhiker avionics plate, and the SEM-15 canister. On the aft side was the G-761 canister containing experiments from Argentina, the PSRD synchrotron detector (a prototype for the AMS antimatter experiment which will fly on Station later), and the COLLIDE-2 and SEM-11 canisters. The SEM (Space Experiment Modules) are collections of high school experiments. LMC, the Lightweight MPESS Carrier carried four canisters with materials science and technology experiments: SEM-12, G-785, G-064 and G-730. In addition, an adapter beam on the starboard sidewall carried G-221 and G-775, with materials science and biology experiments.

Raffaello was transferred back to the Shuttle payload bay on December 14. Endeavour undocked from the Station at 17:28 UTC on December 15 and made a half loop around the station before making a small separation burn at 1822 UTC. The Starshine-2 reflector satellite was ejected from the MACH-1 bridge in Endeavour's payload bay at 1502 UTC on December 16. Endeavour landed on runway 15 at Kennedy Space Center at 1755 UTC on December 17. The Expedition 3 crew of Culbertson, Dezhurov and Tyurin returned to Earth aboard Endeavour, leaving the Expedition 4 crew of Onufrienko, Bursch and Walz in charge of the Station.

"Uborka", normally done on Saturdays, includes removal of food waste products, cleaning of compartments with vacuum cleaner, damp cleaning of the Service Module (SM) dining table, other frequently touched surfaces and surfaces where trash is collected, as well as the FE's sleep station with a standard cleaning solution; also, fan screens and grilles are cleaned to avoid temperature rises. Special cleaning is also done every 90 days on the HEPA (high-efficiency particulate air) bacteria filters in the Lab.) Additional Details: here....

After setting up the video camera gear for covering their CEVIS cycle ergometer workout, Peggy Whitson and Dan Tani activated the OUM-PFE (Oxygen Uptake Measurement - Periodic Fitness Evaluation) equipment at the HRF-2 (Human Research Facility 2) rack, including the HRF PFM/PAM (Pulmonary Function Module/Photoacoustic Analyzer Module), Mixing Bag System and GDS (Gas Delivery System). Both crewmembers then completed the evaluation protocol, wearing HRMs (Heart Rate Monitors), with each one in turn acting as subject and operator, obtaining measurements on themselves on the CEVIS cycle ergometer. (The operations were documented with photo and video. Later, Peggy and Dan updated the evaluation protocol, deactivated & stowed the gear, including photo/video equipment, and powered down the OUM-PFE laptop. Purpose of OUM-PFE is to measure aerobic capacity during exercise within 14 days after arrival on ISS, and once monthly during routine PFEs. The data allows exercise physiologists & flight doctors to assess the crew's health & fitness and to provide data for modifying & updating crew-specific exercise regimes. PFE-OUM is a collaborative effort between NASA and ESA (European Space Agency).) Additional Details: here....

Before breakfast, CDR Peggy Whitson & FE-2 Dan Tani accessed the SLEEP experiment (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) software for data logging, completing questionnaire entries in the experiment's laptop session file on the HRF-1 laptop for later downlink. (To monitor the crewmember's sleep/wake patterns and light exposure, Peggy and Dan wear a special Actiwatch device which measures the light levels encountered by them as well as their patterns of sleep and activity throughout the Expedition.

(The test, using the RSS2 laptop, consisted of switching from the regular 128-byte TM frame to a 206-byte format, for the ground to run tests overnight from RGS (Russian Ground Sites). Tomorrow, in part 2 the FE-1 will reconfigure the BSR-TM back to 128-byte format.)

Afterwards, Malenchenko recorded the post-EVA radiation readings from the Russian EMU-worn plus one background 'Pille-MKS' dosimeters in a log table for subsequent downlink to the ground.

CDR Whitson & FE-1 Malenchenko started off on today's light-duty schedule with another standard 30-min Shuttle RPM (R-bar Pitch Maneuver) skill training, Peggy's third, Yuri's fourth, using DCS-760 digital still cameras with 400 & 800mm lenses at Service Module (SM) windows 6 & 8 to take imagery of documented EO (Earth Observation) targets facing the velocity vector (in flight direction). Afterwards, Peggy downlinked the obtained images to the ground for analysis, to be discussed at a subsequent tagup. (The skill training prepares crewmembers for the bottomside mapping of the Orbiter at the arrival of STS-122/1E in December. During the RPM at ~600 ft from the station, the ISS crew will have only ~90 seconds for taking high-resolution digital photographs of all tile areas and door seals on the Atlantis from SM windows 6 & 8, to be downlinked for launch debris assessment. Thus, time available for the shooting will be very limited, requiring great coordination between the two headset-equipped photographers and the Shuttle.) Additional Details: here....

(The test, controlled from the RSS2 laptop, began 11/21 with Yuri switching from the regular 128-byte TM frame to a 206-byte format, for TsUP to run tests from RGS (Russian Ground Sites). Today, in Part 2 as per plan the FE-1 returned the BSR-TM to the nominal 128-byte format.)

Malenchenko also transferred measurements & imagery from the ESA/RSC-Energia experiment ALTCRISS (Alteino Long Term monitoring of Cosmic Rays on the ISS) to OCA for subsequent downlink to the ground, after yesterday's first repositioning of the spectrometer. (ALTCRISS uses the AST spectrometer to monitor space radiation in the Russian segment (RS).) Additional Details: here....

EVA-12 'Charlie' was completed fully successfully in 7 hrs 4 min, accomplishing all objectives & get-ahead tasks. As a consequence, Node-2 Harmony was fully activated by the ground, one day earlier than originally planned, enabling interior activations by the crew tomorrow.

During the spacewalk, CDR Peggy Whitson (EV1) and FE-2 Dan Tani (EV2), supported by FE-1 Yuri Malenchenko as intravehicular (IV) crewmember, connected and configured the second half of the Node-2 fluid, power, and cooling jumpers (the first half was accomplished on EVA-11 'Bravo' on 11/20). Specifically, the spacewalkers - Additional Details: here....

The FE-1 started his day by recording post-EVA radiation readings from the Russian 'Pille-MKS' dosimeters in the two spacesuits worn by Whitson & Tani during yesterday's spacewalk and from one background dosimeter. Measurements were logged in a table for subsequent downlink to the ground.

In the SM (Service Module), Malenchenko afterwards activated the Kenwood D700 amateur radio station and started the program for the Russian SHADOW-BEACON (Tenj-Mayak) experiment. (Objective of the experiment is the automatic retranslation of time tag (pre-planned executable) packets from ground stations. SHADOW (or ECLIPSE), sponsored by Roskosmos and its leading Moscow research organization TSNIIMASH (Central Research Institute of Machine Building), employs VHF amateur radio (ham) operators around the globe (via ARISS/Amateur Radio on ISS) to help in observing refraction/scattering effects in artificial plasmas using the method of RF (radio frequency) sounding in space experiments under different geophysical conditions. This is the experiment's second run, after Flight Engineer Mikhail Tyurin conducted it first on Expedition 14 in November 2006.) Additional Details: here....

ff-duty day for CDR Whitson, FE-1 Malenchenko and FE-2 Tani. Underway: Week 6 of Increment 16. Having passed the Day 30 mark in her flight, CDR-16 Whitson began her second session with the NASA/JSC experiment NUTRITION w/Repository, for which she had to forego exercising and food intake for eight hours. (After collecting an initial urine sample, Whitson, assisted by Dan Tani, followed it with phlebotomy, i.e., drawing blood samples (from an arm vein) which she first allowed to coagulate in the Repository, then spun in the HRF RC (Human Research Facility/Refrigerated Centrifuge) and finally placed in MELFI (Minus-Eighty Laboratory Freezer for ISS). The RC was later powered off after a temperature reset to limit wear on the compressor, and cleaned (see RC troubleshooting, below). The equipment was then stowed. NUTRITION activities today included the required 24-hour data urine collection by Whitson, by securing samples during the day, all stored immediately in MELFI. The Clinical Nutritional Assessment profile currently required on all U.S. Astronauts collects blood and urine samples preflight and postflight. NUTRITION expands this protocol by also capturing inflight samples and an additional postflight sample. Furthermore, additional measurements are included for samples from all sessions, including additional markers of bone metabolism, vitamin status, and hormone and oxidative stressor tests. The results will be used to better understand the impact of countermeasures (exercise and pharmaceuticals) on nutritional status and nutrient requirements. The Clinical Nutritional Assessment profile (MR016L), first started on two Mir crewmembers and then on all ISS US crews, nominally consists of two pre-flight and one post-flight analysis of nutritional status, as well as an in-flight assessment of dietary intake using the FFQ (Food Frequency Questionnaire). The current NUTRITION project expands MR016L testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.)

(The FE-2 configured the hardware to allow the ground to perform ground commanding to the MLC (Microgravity Science Glovebox Laptop Computer) for diagnostic testing and to develop recovery steps for the ECU (Electronic Control Unit) to be reprogrammed correctly.)

(SONOKARD objectives are stated to (1) study the feasibility of obtaining the maximum of data through computer processing of records obtained overnight, (2) systematically record the crewmember's physiological functions during sleep, (3) study the feasibility of obtaining real-time crew health data. Investigators believe that contactless acquisition of cardiorespiratory data over the night period could serve as a basis for developing efficient criteria for evaluating and predicting adaptive capability of human body in long-duration space flight.)

This includes inspection and audio function checks of all comm panels (PA) in and between the Service Module (SM), FGB and Docking Compartment (DC1), VHF receiver tests, and an audit of headsets. (The "Voskhod-M" STTS enables telephone communications between the SM, FGB, DC1 and U.S. segment (USOS), and also with users on the ground over VHF channels selected by an operator at an SM comm panel, via STTS antennas on the SM's outside. There are six comm panels in the SM with pushbuttons for accessing any of three audio channels, plus an intercom channel. Other modes of the STTS include telegraphy (teletype), EVA voice, emergency alarms, Packet/Email, and TORU docking support. Last time done 4/15/07 by Yurchikhin & Kotov.)

(After yesterday's hardware setup, leak checking of the electronics box and evacuation of the vacuum work chamber (ZB) with the turbopump, the CDR conducted more testing and calibration, uploaded new software from a USB stick to the payload laptop, checked out the software installation and verified the readiness of the experiment. After additional leak checking on the work chamber during the day, Yuri will deactivate the turbopump tonight at ~4:25pm EST. The experiment is performed on plasma, i.e., fine particles charged and excited by HF (high frequency) radio power inside the evacuated work chamber. Main objective is to obtain a homogeneous plasma dust cloud at various pressures and particle quantities with or without superimposition of an LF (low frequency) harmonic electrical field. The experiment is conducted in automated mode. PK-3+ has more advanced hardware and software than the previously used Russian PKE-Nefedov payload.) Additional Details: here....

Found no obvious signs of external damage on cables or hardware of the BGA & BMRMM that might have caused the repeated tripping of circuit breakers (RPCs/Remote Power Controllers), making it more likely that the issue is internal to the hardware or its electrical system; Entered into the S5 truss to disconnect some wiring to allow the ground to perform diagnostic continuity tests, and later reconnected the cables; Temporarily removed 22 protective MLI (Multi-Layer Insulation) covers to inspect the SARJ, its two DLAs (Drive Lock Assemblies), and its 12 TBAs (Trundle Bearing Assemblies), reattaching the covers afterwards, Found most metal shavings around TBA-4 and TBA-5, i.e., metallic, magnetic contamination on the main gear bearing's outboard angled race ring as well as pitting and abrasions on the ring but no obvious damage on the inboard race ring or on the gear teeth themselves. DLA (Drive Lock Assembly) #2 appeared especially 'ugly', i.e., filled with contamination, and, according to the spacewalkers, the further away from the DLA, the less contamination was observed; Took photographs, measured the depth of surface pits with a special probe and collected debris samples; and Deinstalled and removed TBA-5 from its housing under cover #20, using a PGT (Pistol Grip Tool), then brought it inside in a bag for eventual return to Earth aboard STS-122/Atlantis (SARJ can function OK on only 11 TBAs). (Official start time of the spacewalk was 4:50am EST, 70 minutes ahead of the timeline, ending at 11:46am. Total EVA duration (PET = Phase Elapsed Time) was 6h 56min. It was the 100th spacewalk for ISS assembly & maintenance and the 72nd from the station (28 from Shuttle, 50 from Quest, 22 from Pirs) totaling 436h 3m, and the 4th for Expedition 16 (totaling 28h 11m. During the spacewalk, her fifth, Peggy Whitson set a new record of aggregated EVA time by a woman (of 32h 36m) when she exceeded the 29h 18m held by Sunita Williams. After today's EVA, a total of 121 spacewalkers (90 NASA astronauts, 21 Russians, and ten astronauts representing Japan-1, Canada-4, France-1, Germany-1 and Sweden-3) have logged a total of 624h 25m outside the station on building, outfitting and servicing. It was also the 122nd spacewalk by U.S. astronauts. The 100th EVA dedicated to ISS assembly & maintenance originally was to have been conducted by Rex Walheim & Hans Schlegel of the delayed STS-122/1E mission.) Additional Details: here....

Last night, Progress M-61/26P successfully undocked from the ISS at 10:59pm EST (hook opening command: 10:57pm). The separation appeared smooth with no vibrations noted. Downlinked video from the cargo vehicle showed that the docking ring surface was nominal. The first separation burn was performed at 11:03pm and a second separation burn followed at 11:09pm. The spacecraft initially moved aft of the station, then forward, overtaking the ISS on a lower (faster) orbit. 26P will remain in orbit in free flight for 3-4 weeks, continuing to phase out in front of the ISS (about 40 km per orbit) as part of a Russian Earth observation experiment. Additional Details: here....

With the usual dependability, Progress M-62/27P launched nominally this morning at Baikonur at 2:12am EST. Orbit insertion and 3rd stage separation were nominal at ~2:21:30am. Critical antennae and solar array deployments took place without issue. Docking is scheduled on Wednesday, 12/26 (~3:25am EST). Congrats, Baikonur!

Progress M-62 (27P), approaching from below the station, docked nominally at the DC1 Docking Compartment nadir port at 3:14am EST, with automatic AO-VKA orientation antenna retraction, followed by docking probe retraction and hook closure ('sborka') at 3:23am after motion damp-out, while the ISS was in free drift. (Launched 12/23 (2:12am EST), the 27P resupply drone delivered about 2.5 tons of cargo for the ISS crews, including propellants for the Russian thrusters, fresh water, oxygen, food, spare parts, repair gear, life support and science experiment hardware. For the docking, ISS attitude control authority was handed over to Russian MCS (Motion Control System) thrusters at 11:48pm and returned to US Momentum Management at 5:06am. Starting with TV camera activation at ~2:37am (range ~8 km), the KURS TV camera display data overlay failed to show through docking despite attempts by the crew to activate the numerical display. The docking took place nominally, without violation of any joint flight rules, since Malenchenko and Whitson had all numerical data on a laptop before them. Telemetry was also available in TsUP-Moscow.) Additional Details: here....

Also before breakfast, Peggy Whitson, Yuri Malenchenko and Dan Tani performed the periodic Russian biomedical routine assessments PZEh-MO-7/Calf Volume Measurement and PZEh-MO-8/Body Mass Measurement (5th for CDR & FE-1, 4th for FE-2), using the IM mass measurement device which Malenchenko afterwards broke down for stowage. (Calf measurements (left leg only) are taken with the IZOG device, a custom-sewn fabric cuff that fits over the calf, using the knee and lower foot as fixed reference pints, to provide a rough index of deconditioning in zero-G and effectiveness of countermeasures. For determining body mass in zero-G, where things are weightless but not massless, the Russian IM "scales" measure the inertial forces that arise during the oscillatory motion of a mass driven by two helical metering springs with known spring constants. By measuring the time period of each oscillation of the unknown mass (the crewmember) and comparing it to the period of a known mass, the crewmember's mass is calculated by the computer and displayed.)

The FE-2 worked in the Airlock (A/L), starting on a lengthy (2h 25m) troubleshooting procedure on the EACP (EVA/EMU Audio Control Panel), first setting up comm from the A/L, then activating the EACP and connecting it via the 'low clearance' Y-cable to ATU-4 (Audio Terminal Unit, #4) and ATU-6 on the A/L Avionics Rack. After initial testing, the EACP was turned off again. (ATU-6 was installed by Clay Anderson on 10/11/07 in place of a failed unit, and the failed ATU-6 was returned on 10A. The new ATU-6 has been experiencing periodic lockups and PBIT (passive built-in test) faults. Engineering analysis and testing indicate that these issues may be caused by improperly mated J3 & J4 connections, a problem with the address connector, or a dirty fiber-optic connector. There are 3 ATUs in the A/L, one of which must be functional for EVAs, so long as the suited EVA crew has established UHF (Ultra High Frequency) radio communication.) Additional Details: here....

Preparatory to today's pump R&R (Removal & Replacement) of the EHS VOA (Environmental Health Systems/Volatile Organic Analyzer), CDR Whitson rotated the CHeCS rack down for some AAA(Avionics Air Assembly) fan/filter and smoke detector cleaning, before FE-2 Tani performed the VOA IFM (Inflight Maintenance), with filter inspection, preceded and followed by taking CSA-O2 (Compound Specific Analyzer-Oxygen) readings in the affected rack areas. (If the O2 percentage was between 15.7% - 24.1%, Dan was Go to proceed. If not, the ground had steps to be taken to ventilate the area. Ground analysis has shown that the secondary seals in QDs (Quick Disconnects) in the Nitrogen/Oxygen systems do not always seal properly, which can result in an increased N2/O2 concentration behind panels & racks with no ventilation.

This morning, Progress M-62/27P successfully undocked from the ISS DC1 at 5:32am EST 26P will remain in orbit in free flight until 2/15, continuing to phase out in front of the ISS (about 40 km per orbit) in order to support Russian Earth observation experiments. (The separation appeared smooth, with no anomalous behavior reported by the crew. TsUP-Moscow confirmed a 15 second first separation burn complete at approximately 5:35:07anm EST. The ISS returned to US Momentum Management (MM) at approximately 6:46am EST.) Additional Details: here....

Ascent was nominal, all appendages (antennae and solar arrays) deployed nominally and the vehicle reached orbital insertion at 8:12am. 28P is scheduled to dock to the ISS on 2/7 (Thursday) at 9:38am. Congrats, Baikonur!

Mission 1E replanning by MCC-Houston, driven by the one-day delay of the first spacewalk, was completed last night, as follows:

Approved mission extension by one day (i.e., 12+0+2 instead of 11+0+2), resulting in 2/19 (Tuesday) as return date for Atlantis; Limiting resource being oxygen (O2), under further discussion is the option to either extend by one more docked day or transfer the unexpended O2 to the ISS (current O2 margins are estimated to be 11+1+2 plus an additional 20-25 hours. These are still being refined given the insertion of the new FD4); All FD 4 activities moved to FD 5. EVA-1 will be conducted by Stanley Love and Rex Walheim tomorrow, with Campout of the two tonight; Today (FD 4) was replanned and includes 1.5 hrs of focused inspection (FI) of the starboard OMS (Orbital Maneuvering System) pod blanket that has a corner slightly peeled back (the FI, starting at ~ 2:15 pm EST, is planned for 90 min, with additional FI time available on FD 06 if needed); Transfer status: 22% of transfer complete, 6 hours of transfer scheduled for FD 4, expect 35/40 lbs N2 transfer today, 3 CWCs filled. Wakeup time for the ISS crew remains at 4:45am EST, with sleep time tonight 8:45pm. Same times for the Shuttle crew. Additional Details: here....

Mission 1E's EVA-1 was completed successfully by Stanley Love & Rex Walheim in 7hr 58min, accomplishing all its objectives.(During the spacewalk, Walheim (EV1) & Love (EV2) prepared Columbus for unberthing and installation, hooking up electric cables, removing protective covers from the module's docking mechanism and equipping Columbus with the PDGF (Power & Data Grapple Fixture) required for grappling. They also started preparing the NTA (Nitrogen Tank Assembly) for removal, preparatory to replacement with a new NTA on EVA-2 (disconnecting electric cables and two ammonia flex hoses was deferred to Wednesday, but Walheim unfastened two of the four bolts holding down the NTA). Official start time of the spacewalk was 9:13am EST, about 25 minutes ahead of the timeline, and it ended at 5:11pm. Total EVA duration (PET = Phase Elapsed Time) was 7h 58min. It was the 102nd spacewalk for ISS assembly & maintenance and the 74th from the station (28 from Shuttle, 52 from Quest, 22 from Pirs) totaling 451h 11min, and the 6th for Expedition 16 (totaling 43h 19min.) After today's EVA, a total of 125 spacewalkers (94 NASA astronauts, 21 Russians, and ten astronauts representing Japan-1, Canada-4, France-1, Germany-1 and Sweden-3) have logged a total of 639h 33min outside the station on building, outfitting and servicing. It was also the 124th spacewalk by U.S. astronauts.) Additional Details: here....

At ~9:15am EST, the European Columbus laboratory was opened and entered by crewmembers for the first time. (Columbus is permanently attached at the starboard port of Node-2.)

Crew sleep cycle remains at 4:45am - 8:15pm for both crews.

Before breakfast, FE-2 Dan Tani completed his daily access of the SLEEP experiment (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) software for data logging and filling in questionnaire entries in the experiment's laptop session file on the HRF-1 laptop for downlink. (To monitor the crewmember's sleep/wake patterns and light exposure, Dan wears a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout the Expedition.

CDR Peggy Whitson and FE-2-16 Leo Eyharts continued their IMMUNO (Integrated Immune Assessment) experiment, begun on 2/9, with liquid saliva collections, first thing after wake-up and prior to breakfast, drinking and teeth-brushing. All samples were stored at ambient temperature. Dan Tani's IMMUNO liquid saliva collection starts tomorrow morning. (IMMUNO (Integrated Immune Assessment)is a 24-hr. test of human immune system changes, with the objective to investigate immune neuro-endocrine reactions in the space environment by studying samples of saliva, blood and urine using collection kits and the biomedical (MBI) protection kit, to develop and validate an immune monitoring strategy consistent with operational flight requirements and constraints. The strategy uses both long and short duration crewmembers as study subjects. The saliva is collected in two forms, dry and liquid. The dry samples are collected at intervals during the collection day using a specialized book that contains filter paper. The liquid saliva collections require that the crewmember soak a piece of cotton inside their mouth and place it in a salivette bag; there are four of the liquid collections during docked operations. The on-orbit blood samples are collected right before undocking and returned on the Shuttle so that analysis can occur with 48 hours of the sampling. This allows assays that quantify the function of different types white blood cells and other active components of the immune system. For cold storage, samples are secured in the MELFI (Minus-Eighty Laboratory Freezer for ISS). Also included are entries in a fluid/medications intact log, and a stress-test questionnaire to be filled out by the subject at begin and end. Urine is collected during a 24-hour period, conventionally divided into two twelve-hour phases: morning-evening and evening-morning.) Additional Details: here....

Mission 1E's EVA-2 was completed successfully by Rex Walheim & Hans Schlegel in 6h 45m, accomplishing all its objectives and get-aheads.(During the spacewalk, Walheim (EV1) & Schlegel (EV2) removed the new NTA (Nitrogen Tank Assembly) from the Shuttle PLB (Payload Bay), 'flew' it to the CETA (Crew & Equipment Translation Aid) cart for transfer to the P1 truss, installed it in place of the failed NTA, which they returned via CETA for stowage in the PLB, and performed Get-Aheads, viz.: Clean up Lab MMOD (Micrometeoroid/Orbital Debris Shield) & install Columbus Trunnion Covers.) Official start time of the spacewalk was 9:27am EST, about 8 min ahead of the timeline, and it ended at 4:12pm. Total EVA duration (PET = Phase Elapsed Time) was 6h 45min. It was the 103rd spacewalk for ISS assembly & maintenance and the 75th from the station (28 from Shuttle, 53 from Quest, 22 from Pirs) totaling 457h 56min, and the 7th for Expedition 16 (totaling 50h 04min). After today's EVA, a total of 127 spacewalkers (95 NASA astronauts, 21 Russians, and 11 astronauts representing Japan-1, Canada-4, France-1, Germany-2 and Sweden-3) have logged a total of 646h 18min outside the station on building, outfitting and servicing. It was also the 125th spacewalk involving U.S. astronauts.) Additional Details: here....

Mission 1E's EVA-3 was completed successfully by Rex Walheim & Stan Love in 7h 25m, accomplishing all its objectives and get-aheads.(During the spacewalk, Walheim (EV1) & Love (EV3) transferred the European SOLAR (Solar Monitoring Observatory) and the EuTEF (European Technology Exposure Facility) to the COL EPF (Columbus Orbital Laboratory External Payload Facility), retrieved the failed CMG (Control Moment Gyro) for stowage in the Shuttle PLB for return, installed COL worksite interface fixtures and handrails, inspected a suspected sharp-edged MMOD impact site on an Airlock (A/L) handrail (#508), and inspected, photographed and took samples from the failed starboard SARJ (Solar Alpha Rotary Joint) race ring and covers not yet inspected before. Official start time of the spacewalk was 8:07am EST, about 28 min ahead of timeline, and it ended at 3:32pm. Total EVA duration (PET = Phase Elapsed Time) was 7h 25min. It was the 104th spacewalk for ISS assembly & maintenance and the 76th from the station (28 from Shuttle, 54 from Quest, 22 from Pirs) totaling 465h 21min, and the 8th for Expedition 16 (totaling 57h 29min). After today's EVA, a total of 129 spacewalkers (97 NASA astronauts, 21 Russians, and 11 astronauts representing Japan-1, Canada-4, France-1, Germany-2 and Sweden-3) have logged a total of 653h 43min outside the station on building, outfitting and servicing. It was also the 126th spacewalk involving U.S. astronauts.) Additional Details: here....

CDR Peggy Whitson performed her final INTEGRATED IMMUNE blood collection, assisted by MS1 Leland Melvin, right before hatch closure. FE-2 Dan Tani will continue his saliva collections, both liquid and dry, and blood collections aboard the Atlantis all the way home FE-2-16 Leo Eyharts transferred his and Peggy's saliva return pouches and blood sleeves as well as Dan's saliva collection kit to the Shuttle for return.

STS-122/Atlantis and ISS are flying in separate orbits again (Flight Day 12 for STS-122/1E)

After final preparations on both sides of the hatches (closed yesterday on ISS side at 1:03pm EST), Atlantis this morning undocked smoothly at 4:27am from PMA-2 (Pressurized Mating Adapter 2), after a total docked time of 11d 13h 42m. (For undocking, the station was turned from -XVV through ~180 deg to +XVV ZLV (+x-axis in velocity vector, z-axis in local vertical) at ~3:30am, put briefly on free drift for the undocking, and then maneuvered to 1E Stage attitude of +XVV TEA attitude at 5:06am.) See picture from Atlantis flight deck, below. Additional Details: here....

STS-122/Atlantis returned to Earth this morning after 12d 18h 22min in space, touching down at KSC on the first landing opportunity at 9:07am EST, after 202 orbits & 5.3 million miles. During the perfectly executed ISS 1E mission, its seven-member crew conducted three EVAs, delivered and installed the European Columbus laboratory, brought up new Expedition 16 crewmember LĂ(c)opold Eyharts and returned his predecessor Dan Tani who spent 121 days in space (116 on board the station). It was the 121st flight of a Space Shuttle, the 24th Shuttle mission to visit the station and the 29th for Atlantis. Welcome back, Atlantis! Next up: STS-123/Endeavour/1J/A on March 11 with the Kibo laboratory module - Japan/JAXA's BIG day. Additional Details: here....

Progress thrusters (DPO) were inhibited and not involved. (Crew activities focused on TORU activation, inputting commands via the RUO Rotational Hand Controller and close-out ops. TORU lets an SM-based crewmember perform the approach and docking of automated Progress vehicles in case of failure of the automated KURS system. Receiving a video image of the approaching ISS, as seen from a Progress-mounted docking television camera ('Klest'), on a color monitor ('Simvol-Ts', i.e. 'symbol center') which also displays an overlay of rendezvous data from the onboard digital computer, the crewmember steers the Progress to mechanical contact by means of two hand controllers, one for rotation (RUO), the other for translation (RUD), on adjustable armrests. The controller-generated commands are transmitted from the SM's TORU control panel to the Progress via VHF radio. In addition to the Simvol-Ts color monitor, range, range rate (approach velocity) and relative angular position data are displayed on the 'Klest-M' video monitor (VKU) which starts picking up signals from Progress when it is still approximately 7 km away. TORU is monitored in real time from TsUP over Russian ground sites (RGS) and via Ku-band from Houston, but its control cannot be taken over from the ground.) Additional Details: here....

FE-1 Malenchenko updated software on the Russian RS1 laptop HDD (Hard Disk Drive). (After first connecting the A31p to the AGAT external monitor (temporarily disconnected from TP2 laptop), the FE-1 'ghosted' (cloned) its HDD with Vers. 07.05 file structure from a DVD, then updated the RS1 HDD new software from an USB memory stick, and created a copy of the load.)

Afterwards, Malenchenko conducted the periodic/long-term inspection of the pressure hull in the Service Module Working Compartment (SM RO), looking for any moisture, deposits, mold, corrosion and pitting behind panels 107, 109, 130, 134, 135, 138, 139, 452, also underneath the TVIS treadmill (where deposit was discovered earlier) and the cold plates (where SNT and STR lines are installed). (The inspection of the hull surface, which is coated with a primer and dark-green enamel, is done using cleaning napkins to wipe the area in question if required and reporting results to the ground. The hull inspection looks for changed color and cavities; if cavities are found, they are to be measured for depth after cleaning. Digital photographs of the shell before and after the removal of deposits will be made for documentation.) Additional Details: here....

Yi So-yeon, the South Korean SFP (Space Flight Participant), will participate in the experiment. (To monitor the crewmember's sleep/wake patterns and light exposure, crewmembers wear a special Actiwatch device which measures the light levels encountered by them as well as their patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days.)

Also upon wake-up, CDR Whitson started Part 2 (of 5) of the periodic acoustic measurement protocol by recording post-sleep data of the crew-worn acoustic dosimeters, later deploying the dosimeters statically in Node-2, COL (Columbus Orbital Laboratory), and SM (Service Module) near the Central Post for the duration of the day. (Acoustic data must be taken twice per Increment, each time for the duration of the 16-hour crew workday.) Additional Details: here....

MSG was later powered down from its A31p laptop (~8:30am EDT). (CSLM-2 examines the kinetics (e.g., growth rate) of 'competing' particles within a liquid matrix. During this process, small particles shrink by giving up atoms to larger particles, causing the larger particles of tin, suspended in a liquid comprised of molten lead/tin alloy ('matrix'), to grow in size ('coarsen'). This study defines the mechanisms and rates of coarsening that govern the manufacture with metals from turbine blades to dental amalgam fillings.) Additional Details: here....

>>>Today 47 years ago (1961), the first U.S. Astronaut, Navy Commander Alan 'Big Al' Shepard Jr., launched into a suborbital flight of 15 minutes duration, reaching an altitude of 116 miles. This restored faith in the U.S. space program only 23 days after the Soviet space program launched Cosmonaut Yuri Gagarin into orbit around the planet.<<<

FE-2 Reisman supported the Japanese CW/RW (Cell Wall/Resist Wall) experiment in the MSG EMCS (Microgravity Science Glovebox/European Modular Cultivation System), removing and relocating EC1 (Experiment Container 1) and EC2 on Rotor A and Rotor B. (CW/RW operates in the EMCS facility in eight special ECs (Experiment Containers) which Garrett recently (3/30) installed on the centrifuges of the facility. The EMCS rack contains two rotating centrifuges, Rotor A & Rotor B, which can support a wide range of small plant & animal experiments under partial gravity conditions.) Additional Details: here....

(Today's measurements were taken with the AU-1, Kelvin-Video, Iva-6A & TTM-2 instruments near welds along SM (Service Module) structural rings and near the shell ring in the FGB for subsequent downlinking via BSR-TM channel. At the FGB pressurized shell ring, the two cosmonauts also inspected structural elements, equipment, and cable bundles for moisture, mold, or evidence of corrosion. The BAR-RM data are being used for experimenting with ISS leak detection based on environmental data anomalies (temperature, humidity, and ultrasound emissions) at possible leak locations, in order to develop a procedure for detecting air leakage from ISS modules. The payload uses a remote infrared thermometer (Kelvin-Video), a thermohygrometer (Iva-6A), a heat-loss anemometer/thermometer (TTM-2), an ultrasound analyzer (AU-1), and a leak detector (UT2-03) to determine physical background signs of loss of ISS pressure integrity which could be indicative of leaks in the working compartments of the station. Measurements are taken in specific zones in SM PkhO, FGB and DC1, both with lights, fans & ASU pump turned on and off.) Additional Details: here....

Later, the pumping equipment was dismantled and the activities were closed out. (After hooking up the plumbing connecting the 29P water tanks with the SM Rodnik tankage, the water was transferred at first in self-flow (under its own tank pressure), then using a compressor pump via a GZhS gas/liquid separator, to remove air bubbles in the water. The subsequent filling of the empty Progress tanks with urine will be scheduled later.)

After CDR Volkov prepared the auditory test equipment, he, FE-1 Kononenko & FE-2 Reisman took the periodic O-OHA (on-orbit hearing assessment) test, a 30-min. NASA environmental health systems examination to assess the efficacy of acoustic countermeasures, using a special MEC (Medical Equipment Computer) laptop application. It was the second session for the three crewmembers. (The O-OHA audiography test involves minimum audibility measurements for each ear over a wide range of frequencies (0.25-10 kHz) and sound pressure levels, with the crewmembers using individual-specific Prophonics earphones, Bose ANC headsets and the SLM (sound level meter). To conduct the testing, the experimenter is supported by special EarQ software on the MEC, featuring an up/down-arrow-operated slider for each test frequency that the crewmember moves to the lowest sound pressure level at which the tone can still be heard. The baseline test is required not later than about Flight Day 14 for each new Expedition and is then generally performed once per month. Note: There have been temporary hearing deficits documented on some U.S. and Russian crewmembers, all of which recovered to pre-mission levels.) Additional Details: here....

In the DC1 'Pirs', the CDR & FE-1 continued preparations for the EVA-20 on 7/10-11, with the DC1 comm links configured for their presence. Activities by Volkov & Kononenko today focused on

Functional testing of the Russian BETA-08 ECG (electrocardiogram) lead cable belts, worn under the Orlan-M suits, using the Gamma-1M medical complex from the PKO medical exam panel, Transmission tests, after setting up the Orlan 'Tranzit' communications links via the suits' BRTA radio telemetry units, with the ground via RGS VHF, for spacesuit voice, telemetry & biomedical parameters; followed by Restoring nominal communications setup in the DC1, and Configuring the backup Orlan #25 for stowage mode, leaving Orlans #26 (FE-1) & #27 (CDR) ready for use on the upcoming spacewalk. In the U.S. 'Quest' Airlock, FE-2 Chamitoff continued post-1J EVA activities, terminating the 13-hr discharge process on the last 16-volt EMU (Extravehicular Mobility Unit) battery in the BCM-3 (Battery Charger Module 3) from yesterday. (BCM-4 is currently nonfunctional. The discharge process, originally handled manually by a crewmember, is an automated procedure controlled from an A31p SSC (Station Support Computer) laptop with a special DOS application.) Additional Details: here....

It was the second session for Volkov & Kononenko, the first for Chamitoff. (The blood samples were drawn from a finger with a perforator lancet, then centrifuged in two microcapillary tubes in the M-1100 kit's minicentrifuge, and its hematocrit value was read off the tubes with a magnifying glass. It is a well-known phenomenon of space flight that red blood cell count (normal range: 30-45%) tends to go down over time. After the exam, the data were saved in the IFEP software (In-Flight Examination Program) on the MEC (Medical Equipment Computer), and Kononenko stowed the equipment.) Additional Details: here....
